youyr best bet would be to build a frame that the casters are welded to and there are no holes in the outer shell of the freezer. some L shaped angle would work nicely for this application and then there would be plenty of support for when the freezer is loaded up with product. Be sure that teo of the casters are lockable and two in the swivel freely.

The hot sides is normal, this is how they expel the heat from inside the freezer, sometimes it may help to use a fan to help cool. Also make sure there is about 12" of room around all sides of the freezer .

If the compressor actually runs for more than a second or two its likely the compressor is bad. Some models had a 5 year warranty and some ten years on the compressor only. The replacement of the compressor is likely beyond your abilities unless you are a service technician.

A typical cost for such a repair can be more than the freezer may have cost you if nothing is under warranty. Good Luck.

Not sure if its the same for all Kenmore freezer models but this may indicate it is in demo mode. To remove this press the up or down arrow three times as fast as possible (within 2 seconds). This will start the compressor, I hope this helps.

No, it's supposed to be hot on its outside: just make sure the airflow around it is good, the compressor and the radiator at the back are clean and the power plug has a good grounding and a proper fuse and all will be OK.
In the worst case scenario you have a malfunctioning defrost resistance that is constantly on and when it will fry it will take the compressor with it, killing the freezer. But only it, the rest of the house and yourself are perfectly fine. If you want to prevent that you will have to dismantle the freezer and disconnect the resistance - without it the ice buildup inside it will be much faster so you will have to stop the freezer for deicing sooner than normal.

About the only things that can be replaced on a chest style freezer are the thermostat, and the starting device for the compressor. if you know where the control is then thump it fairly hard to see if the unit comes on. If unit comes on then you need to replace the thermostat. (control andthermostat are same thing). now if it has the digital display on the door of the freezer do not thump it. Only the newer freezers have those though. Hope this helps
